Derivation of the botanical name:
Urtica, uro, I burn, alluding to the nettle's sting; stinging nettle. Their capability to sting makes them useful for metaphors.
membranacea, membrana, skin, membrane, parchment; skinlike, membranous.
caudata,cauda, tail; having a tail, usually referring to the shape of the inflorescence.
dubia, doubtfull, in the sense of not following the genus pattern.
In the Bible three different Hebrew names are quoted: Sirpad (סרפד)- in Isaiah 55:13; Seravim (סרבים)- in Ezekiel 2:6; Harul (הרול)-Zephaniah 2:9. They are synonyms, the roots s-r-f and h-a-r both meaning 'scorching' or 'burning'.
